WARD(S) INVOLVED: All
DATE OF REPORT: January 8, 2015
REPORT NO.: INS-15-009
SUBJECT: Summary Water Report—January 1St to December 31, 2014
RECOMMENDATION:
THAT the 2014 City of Kitchener Summary Drinking Water Report be received for
information as required by O.Reg.170/03 Schedule 22 of the Safe Drinking Water Act,
AND FURTHER THAT the City of Kitchener provide a copy of the Summary Drinking
Water report to the Township of Woolwich and the City of Waterloo as required by
Schedule 22 of O.Reg.170/03.
BACKGROUND:
As outlined in Schedule 22 of the Drinking Water Systems Regulation (O.Reg.170/03) of
the Safe Drinking Water Act, 2002, a summary report is to be prepared and given to the
members of the municipal council. The following information is required to be included
in this report:
(a) list the requirements of the Act, the regulations, the system's approval and any order
that the system failed to meet at any time during the period covered by the report and
specify the duration of the failures; and
(b) for each failure referred to in (a), describe the measures that were taken to correct
the failure.
The report must also include:
1. A summary of the quantities and flow rates of the water supplied during the period
covered by the report....

REPORT:
The following matters are reported to Council in accordance with the requirements of
the Safe Drinking Water Act, for the period from January 1 to December 31, 2014:
• A Ministry of Environment (MOE) inspection was completed on January 8, 2014
for the Kitchener System and an annual inspection report was prepared on
January 23, 2014. The report did not identify any non-compliances for the
system. The 2015 inspection has not been scheduled.
• There were 34 Adverse Water Quality Incidents (AWQI's) reported in this time
period (see attached Table 1), of which 21 were due to a result of total coliform in
the temporary watermains.
• Temporary watermains are particularly sensitive as they are above ground
systems influenced by the water heating up in warmer temperatures. This may
cause the potential for bacteriological growth. Due to the sensitive nature, all
temporary watermains are sampled on an increased schedule (every 2 weeks at
multiple locations). The additional challenge with temporary watermains is the
sample port is located outside and subject to unsanitary conditions. Although
efforts are made with the design of the ports contamination, sampling is not
completed under ideal sanitary circumstances. The general nature of
reconstruction projects often lead to "false" positives, where the results received
are more reflective of what is on the sampling tap, rather than what is in the
water. Every positive result is reportable and resampling must occur in
accordance with regulations. When the resamples are clear, it is an indication
that the issue was with the sampling port, not in the water.
• The presence of total coliform on a test does not necessarily mean the water is
unsafe to drink. Coliform bacteria can be found in many different environments.
There are several different types of strains of coliform bacteria. Most are
harmless and do not cause illness. Coliform bacteria is used as an "indicator
organism" to assess the possibility of other disease-causing organisms, and their
detection would prompt further investigation and/or corrective action. It is
different than E.coli which is a bacteria only associated with human or animal
faecal matter.
• When total coliform is found, we resample using a different technique which
provides a number of total coliforms for us to analyze in consultation with Public
Health and the Ministry of Environment. Based on a risk assessment of a number
of factors including: the coliform count, chlorine residuals, upstream/downstream
coliform counts, the requirement for a boil water advisory is determined.
• There were ten (10) incidences of the presence of total coliform in a single
temporary watermain on Lang/Springdale. A watermain break occurred on the
watermain servicing the temporary main. The watermain break contributed to the
already sensitive temporary watermain and resulted in a Boil Water Advisory.
• There were three (3) Boil Water Advisories in 2014. Two (2) were precautionary
due to the potential contamination with sewage during emergency repairs
(resamples were clear).
10 - 2
• Dead end watermain flushing is a proactive approach to increase the levels of
chlorine in the distribution system. The water is initially disinfected (primary
disinfection) at the treatment plant and sufficient chlorine is added to protect the
water from microbiological contamination as it travels through the pipes in the
distribution system (secondary disinfection). Low chlorine does not pose a threat
to human health; to have an impact to human health, there must be
microbiological contamination and no, or extremely low, chlorine.
• Lead testing sampling programs were completed in March/April and September/
October 2014. There was one (1) lead exceedance (>10 pg/L) in the distribution
system. The location was re-sampled and came back with levels less than 10 pg
/L (the limit). There were eight (8) residential plumbing exceedances (>10 pg/L)
during the year. The City is not obligated to complete any additional corrective
actions other than reporting, unless directed by the Medical Officer of Health for
the residential plumbing exceedances.
• A summary of the quantities of the water supplied by the Regional Municipality of
Waterloo during the period covered by the report is noted on the attached Table
2. An increase in the variance over the first three months was due to a
combination of the number of watermain breaks (94 compared to an average of
47 on a typical year) and the number of frozen services (160 on bypass-
minimum consumption applied to both the giver and the receiver) and customers
asked to run their water to prevent freezing (average consumption applied to bill).
• June and September increase/decreases are largely a reflection of the weather.
ALIGNMENT WITH CITY OF KITCHENER STRATEGIC PLAN:
The Annual Summary Water Report relates to the Foundation Plan — Efficient and
Effective Government — Communications goal to "Proactively communicate with
Kitchener residents in an effort to share information; educate and engage the public,
and promote enterprises, programs and services, to create a corporate culture where
internal communications is a priority for all City"
FINANCIAL IMPLICATIONS:
None.
COMMUNITY ENGAGEMENT:
INFORM — This report has been posted to the City's website with the agenda in
advance of the council / committee meeting.
The Ministry of the Environment and the Regional Municipality of Waterloo's Community
Department of Health have been informed of any adverse conditions within the system.
Under Schedule 22 of O.Reg. 170/03, the City of Kitchener is required to provide a copy
of their Summary Report to each Municipality to which it supplies water, namely the
Township of Woolwich and the City of Waterloo.

A similar report - The City of Kitchener Water Distribution Annual Report is provided
electronically on the Kitchener Utilities website, and hard copy is available at the
Kitchener Operations Facility (131 Goodrich Drive). Residents are informed via a
newspaper ad.
